Sacrum magnetic resonance imaging for low back and tail bone pain: A quality initiative to evaluate and improve imaging utility

Figure 2 Axial T1 and coronal STIR images demonstrate mild bilateral sacroiliac joint degeneration. This patient was also noted to have incidentally noted lower lumbar spine degeneration, for which he subsequently underwent a dedicated lumbar spine magnetic resonance. A: Axial T1 image; B: Coronal STIR image.
